Re: AIX Upgrade, what is regression?

Yeah, I saw that, and looked up IY84335 on IBMLink, and saw that it
didn't pertain to us.

But if you get TL5, be sure to get SP1 on top of it. We found that
5300-05-00 was quite unstable, and backed out to 5300-04-03. The newly
available 5300-05-01 should make things a lot better.

I am getting ready to upgrade our lab environment to AIX 53 TL5. I'm
looking at the files to download, and there is a "Special Notice". The
special notice says:

This package contains one or more fixes that are known to cause regression.
The regression may affect your system. Emergency fixes may be available for
these known problems from the Interim fix management page. Reference APAR
number(s) IY84335.

What do you think "regression" means? Is that some form of testing or is
that some sort of fallback?

TIA for any input.
